SPECIFICATION forming part of Letters Patent No. 282,199, dated July 31,18 83. Application filed September 29, 1882. (No model.) Patented inCanada August 23, 1882, No. 15,360.

. T at whom it may concern:

Be it known that I, WILLIAM w. KITeHEN,

of West Union, inthe county of Fayette and State of Iowa, have inventedanew and useful these walls, when the churn is in action, are,

Improvement'in Ohurns, andI dohereby declare that the following isafull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming part of this specification.

My invention relates to an improvement in that form of churns which haveno dasher, but in which the butter globules are released by the impactof the cream in being dashed from one side to the other of thereceptacle by an oscillatory movementof the latter.

My invention consists in the peculiar form of the cream-receptacle, andin the peculiar combination, with the same, of a pendulum for securinguniformity in the oscillation of the churn, as will be hereinafter fullydescribed.

Figure 1 is an end elevation; Fig. 2, a side elevation, andlifig. 3avertical section through the line a; an of Fig. 1.

A represents the cream-receptacle or body of the churn, which iscomposed of two rectangular boxes of exactly equal size, joined togetherat right angles at one edge, forming twopockets or receptacles, I I,divided by a double inclined central ridge. The walls a a of thereceptacle, which formthe bottoms of each box, are inclined to thevertical when the churn is in the normal position of rest, and

each exactly at rightangles to the line of discharge from the otherpocket, so that the cream, in being dashed against said wall at rightangles, secures the best effect of impact for bursting or liberating thebutter globules. The

walls b b of the receptacle, or outer walls of the two boxes, it will beseen, are also inclined to the vertical when the churn is in the normalposition of rest, and when the cream is in the F, through which thecream is introduced.

The cream-receptacle as thus described is supported by trunnions D D upon a suitable frame, B, upon which it is free to oscillate. Thesetrunnions constitute the bearings upon which the case oscillates, andsaid trunnions are exso that the cream inbeing dashed from one pocket tothe other is discharged over the center of oscillation, and thereby ismade to have a stronger vertical falland better impact against thebottom cof the other pocket. This relation of the two boxes to eachother and the apex of the ridge to the center of oscillation also makesthe churn dash its contents quickly from one side to the other withoutthe expenditure of so much power in raising it as is required in otherforms of case acting upon this general principle. I

C is a pendulum having weighted end B, which pendulum is detachablyfastened to the bottom of the churn-receptacle by being fastened in across-bar, G, bymeans of apin,while its upper end is seatedin a recessedblock, d, at the apex of the triangle under the doubleinclined bottom.

In operating my churn as thus described the body portion is oscillatedby hand or otherwise, which causes the cream in one pocket or receptacleI to be poured or dashed with some violence against the wall a of theother pocket, and then upon the next movement is dashed upon thewall aof the first-named pocket, and so the action is continued as the churnoscillates until the churning is finished, which is effected in a veryshort time. in this action gives uniformity to the oscillation, and, inacting as a counter,-balance when one receptacle I is full, assists theoperator in The pendulum transferring the contents to the otherreceptatinctive in the form of the cream-chamber as constructed of tworectangular boxes joined 2 assua e at right angles to each other, whichcauses the walls a a to receive the impact of the cream at right angles,while the walls b prevent the cream from splashing out. It is also dis-5 tinctive in making the apex of the double-inclined ridge in the bottomof the case coincident-with the center of oscillation, as hereinbeforedescribed.

The pendulum, I am aware, is not broadly new in its application tooscillating washingmaehines and to like uses, and I only claim withrespect to this feature its peculiar mode of attachment to my peculiarconstruction of case, in which the socket-block d serves not only tohold the end of the detachable pendulum, but also braces and strengthensthe connection of the two boxes at right angles to form the case. Havingthus described my invention, what I claim as new is 1. The combination,with a supporting-frame having bearings, of an oscillatingcreanrreceptacle formed of two rectangular boxes, II, joined at rightangles to each other, and forming a central double-inclined ridge, withits apex in the center of oscillation, and having end walls, a and 12,substantially as described. 2. The combination, with the two rectangularbox es I I, joined at right angles and forming a central double-inclinedridge, of the block (I, forming a brace at the angle of the two boxes,and provided with asocket for the pendulum, the pendulum G E, and thecrossbar G, substantially as and for the purpose described. I

The above specification of my invention signed by me in the presence oftwo subscribing witnesses.
